Just-world theory research investigates how an individual's world-view influences his/her behavior when confronted with injustice. The purpose of the present study was to examine the utility of multiple continual physiological measurements as predictors of just-world motivated behavior such as immanent justice reasoning (IJR) in a replication of Callan, Ellard, and Nicol's (2006) study. Participants (N=109) were assigned to one of two narrative groups - either an adulterous scenario or a non-adulterous scenario. It was hypothesized that levels of IJR would be higher in the justice-threat than the non-threat condition, and that measures of physiological arousal would predict IJR. Results show that significantly higher responses of IJR were observed during the non-adulterous condition. Additionally, physiological indicators of emotional arousal correctly predicted IJR. These results indicate that physiological measures are useful in assessing justice-threat scenarios, and further research should use such indicators in addition to self-report affect measures.
